Abstract

We have derived a general formula for sensitivity optimization of gravimetric sensors and use it to design a high sensitivity gravimetric sensor using unidirectional carbon fiber epoxy composite (CFEC) guiding layer on (1-x)Pb(Mg_1/3Nb_2/3)O₃-xPbTiO₃ (PMN-xPT) single crystal substrate. The normalized maximum sensitivity (| S m f | λ) max exhibits an increasing tendency with the decrease of (h / λ) opt. For the CFEC/[011]_c poled PMN-0.29PT sensor configuration with λ = 24 μm, the maximum sensitivity | S m f | max can reach as high as 1230 cm²/g, which is about 3 times that of a traditional SiO₂/ST quartz configuration gravimetric sensor.
